1. Material changes are common in the development phase of engineered parts. Consider a component part modeled first using 6061-T6 Aluminum, and then with 1020 Steel. No dimensional changes are made. Do each of the following properties of a solid change with changing material? How?
a. Volume
b. Mass
c. Density
d. Centroid
e. Moment of inertia f. Radius of gyration
2. Vector data and raster data are both used in graphics programs. Which type of data format is better suited for CAD systems that have mass properties capability?
